powerpc64-xtoolchain-gcc (gcc 4.9.1): Expects to find /usr/lib/libc++.so.1 before it is installed there; libcxxrt.so too...

[Mark Millard]

Basic context (more details later):

# freebsd-versino -ku ; uname -ap
su: freebsd-versino: not found
FreeBSD FBSDG5C0 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r279514M: Wed Mar 11 19:23:14 PDT 2015     root at FBSDG4C0:/usr/obj/powerpc.powerpc64/usr/srcC/sys/GENERIC64vtsc-NODEBUG  powerpc powerpc64

Attempting rebuild 11.0-CURRENT r279514 using powerpc64-xtoolchain-gcc's CROSS_TOOLCHAIN=powerpc64-gcc .



(I've broken up the long line below to make it easier to parse.)

*** Error code 1

The the time of the failure the files are actually at:

Notably there is no libcxxrt.so without the .1 suffix anywhere.


More context details:

make -j 8 CROSS_TOOLCHAIN=powerpc64-gcc \
WITHOUT_CLANG_BOOTSTRAP= \
WITHOUT_CLANG_IS_CC= WITHOUT_CLANG= WITHOUT_CLANG_EXTRAS= WITHOUT_CLANG_FULL= \
WITHOUT_LLDB= \

WITHOUT_BINUTILS_BOOTSTRAP= WITHOUT_BINUTILS= \
buildworld buildkernel \
KERNCONF=GENERIC64vtsc-NODEBUG \
TARGET=powerpc TARGET_ARCH=powerpc64

also I retried after the first report with...

make -DNO_CLEAN CROSS_TOOLCHAIN=powerpc64-gcc \
WITHOUT_CLANG_BOOTSTRAP= \
WITHOUT_CLANG_IS_CC= WITHOUT_CLANG= WITHOUT_CLANG_EXTRAS= WITHOUT_CLANG_FULL= \

WITHOUT_BINUTILS_BOOTSTRAP= WITHOUT_BINUTILS= \
buildworld buildkernel \
KERNCONF=GENERIC64vtsc-NODEBUG \
TARGET=powerpc TARGET_ARCH=powerpc64

and it stopped at the same point for the same issue.

( lib/libnv/tests/dnv/tests.cc and lib/libnv/tests/dnv/tests.cc have been updated to -r279760 status to get rid of compile errors.)
